Lasaeola

Lasaeola is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1881. The type species was described under the name Pachydactylus pronus, but was renamed Lasaeola prona when it was discovered that the name "Pachydactylus" was preoccupied. Both this genus and Deliana were removed from the synonymy of Dipoena in 1988, but many of these species require more study before their placement is certain.

43 occurrences of Lasaeola on record. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

43 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

2,480 taxa

The Paleobiology Database records 17 sites for Lasaeola, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

10 references

Each of the 43 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Each entry links to the Paleobiology Database's own record for the work.
